Narrative:

On descent into oma at 6;700 feet; an object appearing to be a drone; but possibly balloons; appeared at 1 o'clock and slightly below us. From our perspective it moved from right to left and went right under our left wing. To me it appeared to have lights on it; which is why my immediate thought was drone. It all happened very quickly and there was no time to maneuver to avoid. We immediately made a radio call to approach; who was currently handling us; to try and pinpoint the exact location. No sounds or evidence of impact noticed. I will add that if this was indeed a drone; we better figure it out quickly; as it would be an obvious easy entry; low cost threat to national security.
